• The premise of "Buckle" is a simple one. Florence Welch confesses that in romance she can be reduced to something as small and undignified as - her words- "the buckle on [his] belt." The same woman who can belt her way through the apocalyptic emotional architecture of "Cosmic Love" is also the one admitting that flattery from the wrong man can topple her faster than a stiff breeze.
• Positioned on Florence + the Machine's 2025 album Everybody Scream, "Buckle" sits comfortably among the themes that animate the record: power, sacrifice, romantic imbalance. "Everybody Scream," for instance, wrestles with the relationship dynamic between Welch and her fans. "One Of The Greats," meanwhile, references her feeling undervalued in a male-dominated industry and finding power within herself.
• Welch wrote the song with Mitski, who also supplies background vocals. Welch told BBC Radio 1 that she more or less blurted out an invitation when she learned Mitski was in town: "Do you want to come to the studio and just see what I'm doing?"
• Welch recalled listening to Mitski's song "Bug Like An Angel" while conceptualizing the album and praised her as someone who will not only happily co-write a new song but will also roll up her sleeves and fix an old one. Case in point: "Everybody Scream" didn't become the song it is until Mitski wandered into the room, listened, and gently noted, "I think you need a chorus."
• Over on Absolute Radio, Welch described watching Mitski play the entire foundation of "Buckle" on guitar in one unbroken sweep. There was something in the way she played it that demanded preservation. "I tried adding more production to that song," said Welch. "I tried adding synths, there was a world where it could've become more of a pop song but there was something about the quality with which she played it, I was like, 'I want that front and center.'"
• Aaron Dessner (Taylor Swift, Ed Sheeran) produced the track. Under his touch, "Buckle" becomes one of the album's quietest, most fragile moments.
• The music video is as intimate as the song. Directed by Autumn de Wilde, it's a single, unbroken close-up of Florence in a mesh veil, singing directly into a microphone.
